wlazara Posted February 11, 2006 Report Share Posted February 11, 2006 doing a normal full backup of my exchange server works fine. however mailbox-level backups take FOREVER. it seems that certain mailboxes can take over an hour each! something seems to be getting hung up. any ideas? this is retro 6.5 on win2003sp1/exch2003sp2 thanks, Wes Link to comment Share on other sites More sharing options...
rkoek Posted February 13, 2006 Report Share Posted February 13, 2006 I have this even when backing up the entire thing. running at an appaling 22mb/min Server v 7.5 win2003 fully patched PIII 1266Mhz 1Gb ram Client win2003 exchange 2003 Xeon 2.8 2Gb ram 60Gb information store.

wlazara Posted February 13, 2006 Author Report Share Posted February 13, 2006 can we get some input from Dantz here? Nate? thanks, Wes Link to comment Share on other sites More sharing options...
natew Posted February 15, 2006 Report Share Posted February 15, 2006 Hi When the backup occurs what is the CPU usage like on the backup server? How much RAM is being used? If you back up only mailboxes to a new or recycled backup set is the performance similar? Thanks Nate Link to comment Share on other sites More sharing options...
wlazara Posted February 15, 2006 Author Report Share Posted February 15, 2006 Hi Nate, thanks for checking in =) the performance issue occurs only with mailbox backups. when i run a normal exchange backup it runs fine. the mailbox backup runs slow regardles of whether it is a normal or recycle backup. the backup server is an IBM xseries 226 with a p4 3ghz and 2 gigs of ram, and an SATA raid5 array running on an adaptec SATA hardware raid controller with 64 megs of cache. retrospect is using about 350 megs of memory and little to no cpu usage during most of the backup. I do notice that rtvscan.exe has 20-30% cpu usage during much of the backup. could this affect things? odd that it wouldn't slow down the normal exchange backups, or my file server backups though... only the mailbox backups is ridiculously slow. and it's not even that the actual mailbox backups are slow - it's more that certain mailboxes hang up the server forever, and others go very quickly... thanks Nate, Wes Link to comment Share on other sites More sharing options...
wlazara Posted February 15, 2006 Author Report Share Posted February 15, 2006 looks like the rtvscan.exe was a temporary thing, it only was running for about a minute in the middle of the backup, now it is 0% cpu util... Link to comment Share on other sites More sharing options...
rkoek Posted February 20, 2006 Report Share Posted February 20, 2006 CPU usage 2-3%, memory 373Mb used. Link to comment Share on other sites More sharing options...
vksmjones Posted February 22, 2006 Report Share Posted February 22, 2006 Mailbox level backups have always been slow here and I only do them right before deleting a user's mailbox. I actually just started a mailbox level backup about 15 minutes ago and it's still 'scanning...' the first mailbox in the list. Full exchange backups don't have the same problem.

rkoek Posted March 1, 2006 Report Share Posted March 1, 2006 Its also slow when backing up First Storage Group. Server: 7.5.251 CPU load mostly below 20%, some spikes goto 33% memory available 600Mb of 1024Mb. Client: win2003, exchange 2003, both fully patched CPU load 2% network load 1% memory available 317Mb of 2048 Please give me some respons...

rkoek Posted March 8, 2006 Report Share Posted March 8, 2006 EuroSupport e-mailed me to try and install the 7.0 CLIENT in stead of the 7.5 client. This worked wonders, I went from 20 to 520MB per minute. Thank you. Link to comment Share on other sites More sharing options...
wlazara Posted March 8, 2006 Author Report Share Posted March 8, 2006 i have 6.5 server - can i use 7.0 client? -Wes Link to comment Share on other sites More sharing options...
nekr0phage Posted March 8, 2006 Report Share Posted March 8, 2006 Hi Wes, A 6.5 server will be able to connect to a 7.0 or even 7.5 client, however I have no idea whether this would improve backup speeds at all. That is something that you'll have to test to find out. Link to comment Share on other sites More sharing options...
lllxm Posted July 10, 2006 Report Share Posted July 10, 2006 Where can I download the 7.0 client to have a try? Link to comment Share on other sites More sharing options...
lebisol Posted July 12, 2006 Report Share Posted July 12, 2006 brick levels will Always take a long time...think of it as backing up into pst. - item by item. :-| Nature of the beast. However, I had a simmilar issue and as it turns out it was a matter of user account used to backup mailboxes. It misteriosly worked for about 2 months (misconfigured) and then it degraded in speed and finally errored out totally. 1. Confirm/configure that correct user is used see thread #72699 2.Reinstall the client and then re-license the exchange ( I saw no diff. performance between clients 7.0 and 7.5 but I stuck with 'the latest & greatest') All the best!
